HIV can usually survive in the foreskin of the penis. HIV is mainly found in the blood, semen, vaginal secretions, cerebrospinal fluid, thoracic and abdominal fluid, and breast milk of AIDS patients and AIDS-infected patients, and is mainly transmitted through sexual contact, blood transmission, and mother-to-child transmission. If a person is circumcised and has sexual intercourse with the patient, HIV may pass through the vaginal secretion, contaminate the virus into the penile foreskin, and cause the body to be infected, so HIV can survive in the penile foreskin. If the AIDS patient is circumcised, HIV may also be present in the foreskin and can be transmitted to the other person through sexual intercourse. If you have an unclean sex life, you should go to the hospital in time for examination, early detection and early intervention.
